[gentoo-dev] How do I keep multiple versions of modules?

[Avi Schwartz]

Sounds strange, but not so.

The problem happened when I built the 2.4.19 kernel.  I had to rebuild
the pcmcia and alsa modules as well.  Guess what, I had some problems
with 2.4.19 (actually the problem is vmware and not the kernel.  vmware
will not build the modules since it uses malloc.h which was depriciated
in 2.4.19).  So I decided to boot 2.4.18.  Suddenly none of the alsa
modules would load.

What happens is that when I built the alsa modules for 2.4.19, the
installation program removed the previous version and therefore the
modules where gone from the /lib/modules/2.4.18 hierarchy.

Kernel modules should be special and if you rebuild a module, it should
remove the module only for the currently running kernel hierarchy and
not from a different kernel version.

Is this even possible with the poratge system?

I wasn't sure where I should post this, so I crossposted to user and
dev.

True.  I suspect that nobody had thought of it yet.

Not right now, although such functionality shouldn't be hard to add.

Please post your comment as a "bug" on bugs.gentoo.org.  You have
a good point, and it would be a shame for it to get lost.

I did, but put it off for post-1.0 :-)

One solution: where the modules have a separate ebuild (like nvidia-kernel, 
not like pcmcia-cs - but they can be split), set SLOT=KERNEL_VERSION and 
(once we have full slot functionality in Portage) remerging won't unmerge a 
different kernel version's modules.
